Abstract (en)
[origin: WO2018229478A1] An analytical test device (12) includes one or more light emitters (13) configured to emit light within a first range of wavelengths (Δλ a ). The analytical test device (12) also includes one or more first photodetectors (14), each first photodetector (14) being sensitive to a second range of wavelengths (Δλ b ) around a first wavelength. The analytical test device (12) also includes one or more second photodetectors (15), each second photodetector (15) being sensitive to a third range of wavelengths (Δλ c ) around a second wavelength, the second wavelength being different to the first wavelength. The analytical test device (12) also includes a correction module (16) configured to receive signals (19, 20) from the first and second photodetectors (14, 15) and to generate a corrected signal (21) based on a weighted difference of the signals (19, 20) from the first and second photodetectors (14, 15). The analytical test device (12) is configured such that light from the light emitters (13) reaches the first and second photodetectors (14, 15) via an optical path which includes a sample receiving portion (7).
